A bicycle is racing around on a horizontal surface in a circle ofradius 16 m. The force exerted by the road on the bicycle makes anangle of 25 degrees with the vertical. What is its speed?

If the frictional force is one-third the maximum value, what is thecoefficient of static friction?

A 600-kg car is going over a curve with a radius of 120 m that isbanked at an angle of 25 degrees with a speed of 30.0 m/s. Thecoefficient of static friction between the car and the road is0.30. What is the normal force exerted by the road on thecar?

a. 1590 N
b. 3430 N
c. 3620 N
d. 7240 N
e. 5330 N

You find that it takes a horizontal force of 124 {\rm N} to slide abox along the surface of a level floor at constant speed. Thecoefficient of static friction is 0.71, and the coefficient ofkinetic friction is 0.40.



If you place the box on a dolly of mass 5.5 {\rm kg} and withcoefficient of rolling friction 1.5×10-2, what horizontalacceleration would that 124 {\rm N} force provide?

A car rounds an unbanked curve of radius 60 m. If the coefficient of static friction between the road and car is 0.66, then answer the following questions. 

(a) What force provides centripetal force?

    • weight of the car
    • normal force on the car from the road
    • force of static friction 

(b) What is the maximum speed at which the car transverse the curve without slipping?
